Permallon® Avant Orthopaedic Ceramics

Permallon Avant LogoIntroducing Permallon® Avant Alumina Matrix Composite



From CoorsTek Bioceramics, a leading manufacturer of technical ceramic components for the orthopaedic implant device industry, comes Permallon® Avant.

Permallon® Avant is a leading-edge alumina matrix composite developed specifically for use as a ceramic bearing surface for total hip arthroplasty. The microstructure of Permallon™ Avant is engineered to incorporate advanced toughening mechanisms to improve mechanical integrity. Proven to provide excellent wear performance for femoral heads, Permallon® Avant offers favorable mechanical performance as compared to the leading ceramic femoral head material.

The chemical composition and physical makeup of the material is also designed to be biocompatible and stable, and to provide excellent wear performance.

CoorsTek Bioceramics offers standard specifications as well as custom design and manufacturing capabilities for Permallon® Avant orthopaedic hip implant components.

Material BenefitsPermallon Avant Femoral Heads

  • BiocompatibleSuperior axial burst strength
  • No metallic ion generation at bearing surface
  • High hardness for optimum wear resistance
  • Hydrothermally stable

Increased Burst StrengthBurst Strength Permallon Avant

Permallon™ Avant femoral head samples (28-12/14 L tested with a titanium taper) passed fatigue testing and are well in excess of the FDA Guidance for post fatigue burst. The axial burst strength of the Permallon™ Avant ceramic femoral head compares favorably to the leading industry standard material for ceramic femoral heads.1

The Permallon™ Avant ceramic femoral heads were subjected to loading that exceeds physiological conditions. In addition, these components are well in excess of the industry standards for strength.
